Convergence Point
When shooting using individual left and right lenses, the point where the optical axes of the left lens and
right lens intersect is called the convergence point. The difference (parallax) between left and right images
for subjects at the convergence point is zero. During playback, subjects at the convergence point appear
to viewers to be positioned right on the screen. Subjects in front of the convergence point appear to pop
out of the screen, while subjects behind the convergence point appear to recede into the distance.
Accordingly, it is essential to set the convergence point appropriately when shooting in order to effectively
create the popping out and receding sensation during playback.
The camcorder convergence point can be adjusted in the range 1.2 m (4 ft) to
∞
(infinity). You can set the
convergence point to the focus position using a single button push, store multiple convergence points, and
recall convergence points when shooting.
Comfortable 3D Images
For subjects displaced from the convergence point, the parallax becomes larger as the distance from the
convergence point becomes larger. In other words, the closer the subject the more it will appear to pop
out, and the further away the more it will appear to recede into the distance. If the parallax becomes too
large, it becomes difficult for the viewer to combine the left and right images, and not only will the 3D
image appear unnatural but it may also cause eye fatigue and discomfort while viewing. Therefore, in
order to shoot comfortable 3D images for the viewer, it is essential to keep the size of parallax within an
appropriate range.
